Single-shot, simultaneous incoherent and holographic microscopy

In this work, we demonstrate single-shot, simultaneous recording and subsequent retrieval of one incoherent and two holographic (intensity and phase) images from the same camera frame.

Nanometric depth resolution from multi-focal images in microscopy [PDF]

, 2011
We describe a method for tracking the position of small features in three dimensions from images recorded on a standard microscope with an inexpensive attachment between the microscope and the camera.

Automatic Focusing of Off-Axis Digital Holographic Microscopy by Combining the Discrete Cosine Transform Sparse Dictionary with the Edge Preservation Index

Optics
Automatic focusing is a crucial research issue for achieving high-quality reconstructed images in digital holographic microscopy. This paper proposes an automatic focusing method that combines the discrete cosine transform (DCT) sparse dictionary with ...

Label-free spatio-temporal monitoring of cytosolic mass, osmolarity, and volume in living cells

Nature Communications, 2019
Label-free, spatio-temporal imaging of cellular physiological responses is challenging. Here the authors combine digital holographic microscopy with a millifluidic chip and mathematical modelling to quantify cell volume, mass and cell uptake under ...

P-TDHM: Open-source portable telecentric digital holographic microscope

HardwareX
We present the design of a low-cost, portable telecentric digital holographic microscope (P-TDHM) that utilizes off-the-shelf components. We describe the system’s hardware and software elements and evaluate its performance by imaging samples ranging from
